SFP+ Optical Transceiver Specifications
This section provides the general and environmental specifications for the SFP+ transceivers used with
optical cables.
For the general specifications that apply to SFP+ transceivers, see Table B-4. For the environmental
specifications, see Table B-5.
1. Dimensions are presented for only the chassis rack size and service clearance requirements.
2. Combine the chassis, power supply, and fan tray weights for the overall weight of the switch to be installed. Remember to
double the power supply weights if there are two power supplies installed in the FEX.
